➤ Using

strval()

function. • The strval() function is an inbuilt function in PHP and is used to convert any scalar value (string, integer, or double) to a string. We cannot use strval() on arrays or on object, if applied then this function only returns the type name of the value being converted.

$number = 10;
// converts integer into string
$str = strval($number);
echo gettype($str); // outputs:  string

➤ Using inline variable parsing. • When you use Integer inside a string, then the Integer is first converted into a string and then prints as a string.

$integer = 10;
$str = "$integer";
echo gettype($str); // outputs:  string

➤ Using explicit Casting. • Explicit Casting is the explicit conversion of data type because the user explicitly defines the data type in which he wants to cast. We will convert Integer into String.

$num = 5;
$str = (string)$num; // or String
echo gettype($str); // outputs:  string
